Shark Deck #768527 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 39/100 (±10 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Stun
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro/Xyz/Link boss (Lancea, Swordsoul Chengying, Icejade Gymir, Trishula, Dragite) reached through Penguin and Shark starters while hand traps protect the board; Mulcharmy draw-engine card advantage that grinds the opponent out over a long round
• Turn 1 (going first): Open a Penguin or Mulcharmy starter, search through Royal Penguins Garden or Puny/Penguin Squire, and build toward a Synchro boss while holding one or two hand traps for the opponent's first answer
• Turn 2 (going second): Use hand traps (Ash, Droll, Impermanence, Solemn, Ghost Ogre) to strip the opponent's first board, then convert with Raigeki or Harpie's Feather Duster and a boss Synchro
• Recovery: Mulcharmy Fuwalos and Purulia draw on opponent summons, Nopenguin and Puny Penguin recur from the GY, and Mermail King - Neptabyss searches
• After siding: Not available: the deck runs no Side Deck, so there is no post-side plan. Legal size allows 0 to 15 side cards, but none are registered

Why it scores here

The deck reliably opens a functional starter in most hands: the core Penguin and Mulcharmy group of 11 copies has about a 0.69 chance of at least one copy in a 5-card opener, and the searcher group of 14 cards about 0.78 (Inferred, hypergeometric). Its interaction density is high, with about 15 negation and 15 removal effects and 10 hand traps, which earns the interaction and going-second dimensions (Inferred from card text). Conversion is weaker: there are no recorded boards, so ceiling and median output rest on card-text reads only, and 42 and 40 are estimates, not measurements. The deck is penalised for brick risk (about 0.31 full-brick proxy), dilution across 27 distinct main-deck cards with only 1.4% exact-name Shark purity, an empty Side Deck, and an over-limit Ash Blossom. Popularity and archetype label played no part in the score, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Toolbox primary, Stun secondary (not blended numerically; weights taken from Toolbox). Structural ≈ 52, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); engine_conflict (-4). Final formula: No reliable metagame: 0.80*Structural(52) + 0.20*TournamentReliability(45) + ContextModifiers(-12) = 39; deck is Illegal, so this is a theoretical/structural-only score

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High interaction density: about 15 negation and 15 removal effects plus 10 hand traps
• Strong Synchro/Xyz/Link closers at 2700-3300 ATK
• Reliable starter access for the core Penguin and Mulcharmy group (about 0.69 in a 5-card hand)

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring at 3 copies against a limit of 2
• Dilution: 27 distinct main-deck cards and 1.4% exact Shark purity
• No Side Deck, so no post-side plan
• Mulcharmy's 'no cards' condition conflicts with the hand-trap plan
• No recorded combos, so ceiling and median are unmeasured

Critical choke points

• Hand-trap timing: most interaction depends on holding Ash, Droll or Impermanence, which Mulcharmy's condition discourages
• Single-copy Raigeki and Harpie's Feather Duster are the only full-board wipes
• Ash over-limit must be fixed before any legal evaluation applies

Recommended changes

Evidence & confidence

• Verified: Legality: 55 main, 15 extra, 0 side; Ash Blossom over limit (3 vs 2, Semi-Limited); Restricted cards Droll & Lock Bird, Harpie's Feather Duster and Monster Reborn each run one legal copy; Card text and stats for all listed cards; Archetype purity 1.4% exact-name; 69 off-archetype copies
• Observed: Usage: Crystal Shark and Mulcharmy Fuwalos/Purulia are core for the archetype, and the deck runs them
• Inferred: Hypergeometric starter access 0.69 (core) and 0.78 (searcher); Full-brick proxy about 0.31; Interaction density from card text (about 15 negation, 15 removal); Going-second advantage from hand traps
• Provisional: Meta and format fit (D13) with no dated sample or tournament link
• Data gaps: no combos supplied: combo floor, median and ceiling are text-only inference no tournament link: archetype meta-share and per-pilot record are absent no win-rate telemetry (going-first/second, matchup, brick and starter rates) no side deck registered, so post-side performance cannot be assessed Meta Power is provisional unless a dated metagame sample is supplied
